Preliminary connected-load and demand planning for circuits.
Appliance watts or amps, voltage, continuous loads and operating assumptions.
Connected load, estimated current and a planning comparison.
Do not use this as a final code calculation; circuit, conductor, breaker and service sizing require qualified review.
See the estimated project quantity from your measurements.
Add waste and round to complete bags, boxes, cans, bundles or delivery quantities.
Review product coverage, site conditions, local requirements and supplier details before ordering.
Estimate watts, amps and apparent load for preliminary planning.
Single-phase real power ≈ V × A × power factor.
This is a preliminary load estimate, not an electrical code compliance calculation. Conductor sizing, breakers, continuous loads and service requirements must be checked against applicable local electrical codes.
Estimate electrical load from voltage and current or appliance wattage. Start with the actual dimensions or load values from the project, keep the units consistent, and change the default assumptions when the product label or supplier sheet gives you a more accurate value.
This page is for early material planning. The result can change with openings, layout, cuts, waste, product yield, density, packaging, access, installation method and site conditions. It does not replace structural design, permitted drawings, manufacturer instructions or a contractor quotation.
For a simple project, enter one measured section first and review the result. If the shape is irregular, split it into smaller sections, calculate each section, and add the quantities before applying whole-bag, box, bundle or delivery rounding.
